How do I maintain the security of my password during a session Any learned answer will be highly appreciated. Why phpmyadmin works fine but not my own code (which works only with md5 () or plain text format password) 3. Users.cbc: The initialisation vector adds randomness to the encryption and required for CBC mode. How to decrypt the password which has been encrypted with password () function 2. The field users.password will be hashed using a one-way password hash.Ĭipher & mode: Choosing the best encryption cipher and mode affects the size of both the encryption key and initialisation vector for this how-to we will be using AES-256-CBC which has a fixed block size of 16 bytes and a key size of either 16, 24 or 32 bytes.Ī good encryption key is a binary blob that's generated from a reliable random number generator, like the following example.To store those values in MySQL, consider using BINARY or VARBINARY columns The storage requirements depend on the cipher and mode used. The field users.cbc will store the initialization vector used for encryption. If you had phpMyAdmin access to the site, you could run an SQL command as follows: SdLdCT concat( username, PASSWORD ) AS Title FROM josusers WHIR'.The fields users.name, users.surname and users.email will be encrypted using a symmetric cipher, provided by OpenSSL.A Data table with the following basic fields: users.id, users.name, users.surname, users.email, users.password, users.cbc.I was recently asked by some software engineering students about the security capabilities that PHP (more exactly, version 7), faced with the restrictions that the GDPR establishes in terms of storage and exploitation of data.Īfter a while debating about different methods, we elaborated, together, a system of data storage and authentication in PHP, with encrypted data. ![]()
